Note : I really think it's a bad idea and a waste of time to try to add that kind of feature to a web site. Why? Somebody finds your text interesting and wants to copy it and send it to his email or paste it somewhere to promote something on your site and he'll get a message that feels like "Hey, I don't trust you".

Second, it's so easy to disable JavaScript or just show the source of a page and copy the text from there that this method would only prevent people that knows almost nothing about the Internet to copy the text. And, this is often the people that just wants to send the text to themselves or their friends. If somebody copies content of other websites to put it on its own site, I'm sure he'll be able to disable that "child lock".
